IMPROVEMENT IN MACHINES FOR 'UNTWISTINGE AND SEPARATIN G- HAIR-ROPE.

The Schedule referred to in these Lettere Patent and making part of the same To all whom z't may concern Beit known that we, JOSEPH PARADIS and WIL- LIAM H. DREW, of Brooklyn, in the county of Kings and State of New York, have invented and made an Improvement in Machines for Opening Hair-Rope and the following is declared to be a correct vdescription thereof.

Hair-rope has heretofore been opened principally by hand, because the mechanism that has been devised for performing'that work has done the work very imperfectly, leaving the hair in a tangled, knotty condition, as well as breaking and injuring the ber by the beating operation to which the nutwisted rope has been subjected.

The machine heretofore'made for this purpose has also occupied a large space, and required considerable attention.

Onr invention is for opening the hair by the actionv of a blast of air, thereby avoiding injury to the same, and thoroughly separating the curled hair; at the same time the machine takes but little space, and requires a small amount of attention.

In the drawing- Figure 1 is a vertical section of the blowing and separating-apparatus.

(ligure 2 is a section of the untwisting mechanism an Figure 3 is a front view of thelast-named mechanism. i

We have shown our untwisting device as adapted to three spools of rope, but the same may have more than that number, orl only act upon one spool; we will therefore describe'the mechanism with reference to one spool.

Ahead or frame, a, supports a friction-wheel, l), and its shaft, that are .revolved by the pulley c, and the reel or spool d, that contains the twisted hair-rope, is mounted iu the frame e, which frame e is revolved by the contact of the pulley f with the friction-Wheel b.

The axis upon which the frame e revolves is made as a gudgeonthat projects eccentrically from a disk that is set in the frame .a,so ythat the pulley f can be brought into contact with the wheel l) by turning the eccentric disk by the lever. g, or the reverse motion vstops the revolution of the frame e.

The pin i, that passes through the reel d, is made with a head at one end, and a latch at the. other, so

as to be held in place, 'and the rope is led off between the spring clipping rollers r r that are employed to keep the rope from nntwisting between the spool and these rollers r. 4

A cross-bar may bc employed, atv s, for the hairrope to pass beneath, and a ring-formed opening may be made at the apex ofthe frame e for the rope to pass through, so as to prevent the rope slipping ont from between thc rollers fr, but this ring may be -dispensed with.

qWe apply a friction-spring, at n, to the reeld, so as to prevent the rope unwindiug too fast.

The rope of hair passes from the unwinding-framc to the pair of feeding and drawing-rollers l l, that are mounted upon a suitable frame, m, and driven by power applied to the wheel 11, or otherwise.

The upper roller is to be weight-ed suiiciently to hold the hair-rope against the untwisting action of the frame c, and cause the rope to be drawn along with regularity.

It will now be understood that the hair-rope passes out of the rollers l Z in an untwisted condition, and is to be opened or separated so as to prevent thc hair twisting or coiling together again.

le have discovered that a powerful current of air directed upon the hair at this point is the most effective means of separating the same, because the hair is not matted or knotted thereby, but it is kept cony stautly `opened and drawn out unt-il the separate bers are detached and blown away into a receiving-room.

This operation is more perfect, rapid, and cheap, than the picking performed by hand.

As a convenient means for directing a current of air upon the hair, we employ, and have shown, therevolving blower-t within the case u, and driven by coinpetent power.

`The oase at c may bc adjusted by set-screws so as to place the same nearer to or further from, the rcvolving fans, and thereby increase or diminish the action of the air upon the fiber.

XVe do not desire the.y hair to come in contact with the edges of the fans, because the air is sufiicieut for the separation of the hair, and hence the hair cannot be c ut or injured.

' We claim as ourinventio'nlf'lhe means herein specified for nntwisting hairrope, 'consisting of tl1el1oldingrollei's 1j rin the revolving' frame e that carries the reel of the rope, in combination with the lraivingrollers ll, substantially as specilied, so that the hair shall be delivered from these rollers l in an untwistcd condition, as set forth.

V2. In combination with the foregoing, thefrictionwheel l), pulley f, and eccentric, as and for the purposes specilied.

3. The combination, with mechanism for untwisting substantially' as set forth.
